(structural member 1)
Next, be described with reference to the structure of Fig. 2 to the structural member 1 of present embodiment.Fig. 2 is the figure of the structure of structural member 1 for illustration of present embodiment.
The carrier member 3 that the structural member 1 of present embodiment is comprised cylindric main component 2 and engaged with the two ends of main component 2 respectively by the electromagnetism draw.
It should be noted that, at this, enumerating the situation that carrier member 3 engages with the two ends of main component 2 is respectively that example is described, but is not limited to this example.In the structural member 1 of present embodiment, as long as at least one carrier member 3 engages with main component 2, the structure with the engaged at end of a side of the main component 2 of cylindrical shape also can be adopted.
In addition, although not shown, main component 2 also can have the cylindrical body from this component branch, thus also can adopt by this cylindrical body joint holder component 3, makes the structure that the carrier member 3 of more than three engages with main component 2 thus.
Carrier member 3 has cylindrical portion 31 and gives prominence to the flank 32 of formation from the outer peripheral face of this cylindrical portion 31.This carrier member 3 is held back close fastening by the electromagnetism draw and main component 2.In addition, also can be formed with bolt hole 33 on flank 32, this bolt hole 33 is for inserting for the bolt being installed on other structural members (front side frame 101 such as, in Fig. 1 or upper side frame 104) linked by structural member 1.In addition, though be not particularly limited, as shown in Figure 2, flank 32 can be set to from the outstanding plate-like portion of the outer peripheral face of cylindrical portion 31.
It should be noted that, in the present embodiment, the cylindrical portion 31 enumerating main component 2 and carrier member 3 is the situation of drum is that example is illustrated, but is not limited to this example.Such as, the section of main component 2 and cylindrical portion 31 also can be elliptical shape, roughly quadrilateral shape etc.
In the structural member 1 of present embodiment, though be not particularly limited, main component 2 is made up of aluminium alloy material or steel.In addition, carrier member 3 is made up of nonmagnetic material.Particularly from the viewpoint of lightness, high strength, preferred carriage component 3 is made up of aluminium alloy.More particularly, as aluminium alloy, preferably use such as AA2000 system, AA6000 system, AA7000 system etc.
In addition, preferred carriage component 3 is extrusions, can be shaped cylindrical portion 31 and flank 32 when not carrying out the cutting based on cutting etc. simultaneously.
At this, further describe the structure of carrier member 3 with reference to Fig. 3 A, Fig. 3 B.Fig. 3 A, Fig. 3 B illustrate the figure of state when observing from the direction of the arrow F Fig. 2 in the structural member 1 of present embodiment, carrier member 3 engages with main component 2.More particularly, Fig. 3 A is the figure that the state that carrier member 3a is engaged with main component 2 is shown, Fig. 3 B is the figure that the state that carrier member 3b difform with carrier member 3a is engaged with main component 2 is shown.
In the structural member 1 of present embodiment, as long as flank 32 is installed on the outer peripheral face of the cylindrical portion 31 of carrier member 3, then without particular limitation of the shape of flank 32.The shape that the opposed ground of pair of ribs 32,32 that such as Fig. 3 A is such correspondingly can be adopted to configure side by side with the shape etc. of other structural members or the flank 32 shown in Fig. 3 B become a flat shape in the side contrary with main component 2.
So, in the carrier member 3 of the structural member 1 of present embodiment, the outer peripheral face of cylindrical portion 31 is provided with flank 32.Therefore, even if carry out the electromagnetism draw to carrier member 3 and main component 2, the rigidity of the root 34 of the flank 32 of cylindrical portion 31 is also higher, and the cut-off of root 34 reduces compared with the cylindrical portion 31 beyond the root 34 of flank 32.
Now, between cylindrical portion 31 inner surface and the outer surface of main component 2 at root 34 place of the flank 32 of carrier member 3, gap is formed with.Such as, in main component 2, equably undergauge does not occur in a circumferential direction, the region contacted in the inner peripheral surface side of the cylindrical portion 31 with root 34 has been partially formed jut.Therefore, when applying the load of direction of rotation to carrier member 3, can prevent main component 2 from rotating in a circumferential direction.It should be noted that, at this, cut-off refers to the size of the diameter that cylindrical portion 31 reduces because of the electromagnetism draw.
(manufacture method of structural member 1)
Next, be described with reference to Fig. 4 A, Fig. 4 B, Fig. 5 A, Fig. 5 B and Fig. 6 manufacture method to the structural member 1 of present embodiment.Fig. 4 A is the figure of the structure of the electromagnetism pipe reduction device 7 of the structural member 1 illustrated for the manufacture of present embodiment, and is the side view of electromagnetism pipe reduction device 7.Fig. 4 B is the figure of the structure of the electromagnetism pipe reduction device 7 of the structural member 1 illustrated for the manufacture of present embodiment, and is the front view of electromagnetism pipe reduction device 7.In addition, Fig. 5 A is the figure of the structure of other electromagnetism pipe reduction devices 17 of the structural member 1 illustrated for the manufacture of present embodiment, and is the side view of electromagnetism pipe reduction device 17.Fig. 5 B is the figure of the structure of other electromagnetism pipe reduction devices 17 of the structural member 1 illustrated for the manufacture of present embodiment, and is the front view of electromagnetism pipe reduction device 17.Fig. 6 is the flow chart of the manufacturing process of the structural member 1 that present embodiment is shown.
First, to using the method for the electromagnetism pipe reduction device 7 manufacturing structure part 1 shown in Fig. 4 A, Fig. 4 B to be described.First, the cylindrical portion 31 of the two ends of main component (inner member) 2 respectively to carrier member (cylindrical member with ribbing) 3 is inserted (the step S11 in Fig. 6).Next, as shown in Figure 4A and 4B, surround by the electromagnetic flux field concentrator 7b of electromagnetism pipe reduction device 7 carrier member 3 (the step S12 in Fig. 6) being inserted with main component 2.More particularly, preferably carrier member 3 is inserted to the inner chamber 7c of the roughly the same shape along carrier member 3 of electromagnetic flux field concentrator 7b.
This electromagnetic flux field concentrator 7b is divided into upper and lower two, is configured with coil electric conductor 7a in periphery.Then, electromagnetic flux field concentrator 7b can make the flux concentrating from coil electric conductor 7a generation.
Next, turn on-switch 9 is also energized, and carries out discharge (the step S13 Fig. 6) from capacitor 8.Thus, big current flows through coil electric conductor 7a instantaneously, from the face that the flux concentrating of coil electric conductor 7a generation is opposed in the outer peripheral face of the cylindrical portion 31 with the carrier member 3 be arranged in electromagnetic flux field concentrator 7b.
Consequently, produce in the carrier member 3 of nonmagnetic material and guide electric current, based on the interaction of this guiding electric current and electromagnetic field, the power (electromagnetic force) of the part draw overlapping with cylindrical portion 31 of main component 2 is played a role.Thus, hold back close fastening to carrier member 3 and main component 2.It should be noted that, in figure 4b, Reference numeral 10 represents the power supply of charging circuit, and Reference numeral 11 represents charge switch.
Now, due to a part for cylindrical portion 31 and the rigidity of root 34 higher, therefore cut-off is likely little than the position beyond the root 34 of cylindrical portion 31.Therefore, main component 2 draw unevenly in a circumferential direction, and carry out holding back close fastening, in the region that the inner peripheral surface side at the root place linked for flank 32 with cylindrical portion 31 contacts, be partially formed jut.Therefore, it is possible to prevent carrier member 3 from rotating in a circumferential direction relative to main component 2 and make carrier member 3 close loosening relative to holding back of main component 2.
Also can position beyond the root (also referred to as linking part) 34 of the cylindrical portion 31 of carrier member 3 at least partially, formed compared with other positions from inner circumferential side towards the thinner wall section (not shown) of the thinner thickness of outer circumferential side.Thereby, it is possible to expand the difference of the cut-off of circumferencial direction further, so can more effectively prevent carrier member 3 from rotating in a circumferential direction relative to main component 2.In addition, also can carrier member 3 is held back to main component 2 close after, by spot welding, MIG spot welding etc. by carrier member 3 and main component 2 local welding, or engaged and local engagement by friction stir spot.In addition, in the scope not producing deformation, also linearly can weld (MIG welding, TIG welding, laser weld) or be engaged into line linearity by friction-stir and engage.Thus, carrier member 3 improves further with the bond strength of main component 2.
In the manufacture method of the structural member 1 of present embodiment, be not limited to the electromagnetism pipe reduction device 7 shown in Fig. 4 A, Fig. 4 B, such as, also can use the electromagnetism pipe reduction device 17 shown in Fig. 5 A, Fig. 5 B.In this electromagnetism pipe reduction device 17, as shown in Figure 5A, coil electric conductor 7a is not set in a part for the periphery of electromagnetic flux field concentrator 17b.Axis from the part that this periphery does not arrange coil electric conductor 7a is formed with coil electric conductor 7a part from periphery winding to coil (with electric conductor around the parallel direction of central shaft) outstandingly to be formed, carrier member 3 can be surrounded.
In the electromagnetism pipe reduction device 7 shown in Fig. 4 A, Fig. 4 B, the periphery that coil electric conductor 7a is configured in electromagnetic flux field concentrator 7b is overall, increase mutually suitablely with the size of the flank 32 of carrier member 3, the size of coil electric conductor 7a also needs to increase, the manufacturing cost increase of coil.About this point, in the electromagnetism pipe reduction device 17 shown in Fig. 5 A, Fig. 5 B, the region that a part of electromagnetic flux field concentrator 17b forms coil electric conductor 7a from winding is given prominence to, and this outstanding part surrounds carrier member 3.Therefore, when use size large flank 32, the size increasing coil electric conductor 7a is not needed yet.Therefore, it is possible to the manufacturing cost by using this electromagnetism pipe reduction device 17 to suppress coil.
Preferred carriage component 3, before being held back close fastening operation by the electromagnetism draw, implements softening process by annealing, quenching etc.By implementing softening process to carrier member 3, the cut-off after the electromagnetism draw increases, and carrier member 3 improves relative to the close power of holding back of main component 2.
Structural member 1 also can carry out the shaping of the electromagnetism draw as required after quenching, carries out artificial aging process afterwards.Thereby, it is possible to improve the intensity of carrier member 3 further.Now, preferred carriage component 3 use 2000 be, 6000 be, 7000 aluminium alloys being.
As described above in detail, in the structural member 1 of present embodiment, under the state that carrier member 3 is fixed on certain position, the electromagnetism draw is carried out.Therefore, do not need weld needed for complicated procedures of forming, can simple and easy and accurately obtain structural member 1.Particularly, also can not produce in the thermal deformation will occurred fastening to main component 2 and carrier member 3 by welding, the excellent structural member of precision 1 can be obtained.In addition, because flank 32 is configured in the outer surface of cylindrical portion 31, therefore carrier member 3 becomes compact.
In addition, carrier member 3 and main component 2 are undertaken holding back close fastening by the electromagnetism draw, exist and to compare with the linking part 34 of flank 32 with cylindrical portion 31 and the larger situation of the cut-off of cylindrical portion 31 beyond this linking part 34.Thus, main component 2 does not have in the circumferential the draw equably, but forms jut in the region contacted with the inner peripheral surface of linking part 34.Therefore, it is possible to prevent carrier member 3 from rotating relative to main component 2.That is, resistance to loading for the load along the circumferential direction applied of structural member 1 can be improved, the structural member 1 that intensity is improved can be obtained.
< second embodiment >
